Here's just some rough statistics based on the Hackage access logs of
september so far, assuming the heuristic each distinct user can be
identified by its IP address (the numbers denote the distinct IP
addresses that accessed Hackage with the particular cabal-install

     89 cabal-install/0.10.2
      1 cabal-install/0.10.3
      2 cabal-install/0.13.3

      3 cabal-install/0.17.0
      1 cabal-install/0.6.2

GHC 7.0 shipped with Cabal-1.10 (and so cabal-install-0.10 is the likely
version used by GHC 7.0 users); so that should give you a hint about how
many users didn't upgrade their cabal-install and stayed with
cabal-install-0.10 (and probably GHC 7.0.x). So there are probably still
a few users left on GHC 7.0...

Otoh, it's nice to see that the latest cabal-install- (which
uses a newer Cabal major version than is shipped with GHC 7.8) is being
used the most for hitting Hackage -- seems the cabal-install "there's a
newer version"-reminder is working quite well...
